standard naming conventions?

is there a standard naming convention in c++?

Yes, there are lots of them in fact! ;)

This is the one I use:

• Variable names begin with a small letter and the first letter of each word in the name afterwards is capital (eg. int avgStudentMarks).
  
• Classes, Structs, Enums and Public Functions are the same as variables, except they begin with a capital letter.
  
• Private & Protected functions are the same as variable names.
  
• Class Member Variables ALWAYS start with m_ (eg. std::string m_FirstName).
  
• Macros & constants are all capitals.

Quick search: http://en.wikipedia.org/wiki/Identif...ing_convention

This is purly programmer preference, but when using a reference, I do this:

Code:

---

rMyName;

---

the small " r " helps to remember I am using a reference to another variable.

Also, with a variable you have declared as "const", use uppercase letters;

Code:

---

const int MAX_ARRAY = 5;

---

Leaving it uppercase ensures you know that you are dealing with a special variable, hence you know it must be constantly assigned a value.

Any reasonably large company or other organization will have it's own conventions.

I personally (when I do "hobby programming" use something similar to cpjust.

One example is Linux, which of course isn't C++, use all identifiers except macros as lower-case, using underscore to split parts of names up, e.g. avg_student_marks.

Another example is Microsoft, where they use a "hungarian notation", where a "pointer to zero terminated string" starts with psz then the name, e.g. pszFileName. All pointers start with p, a character starts with c, an integer with i, structures with "structname", e.g. a "struct rect" would be rectDrawRegion - and a pointer to a struct rect would be prectDrawRegion. This makes it easier to understand what the type of a variable is without looking up at the top of the function. Of course, opponents to this techniqeu would say that it adds "meaningless" info to the variables, since if you already know what type the variable is, then you don't need these "name decorations".

I like joels article about wrong understood vs. useful type of hungarian notation.

There are as many styles as there are programmers. (Yes, I've said that before.)

It's one of those things. Indentation. Whitespace. Naming conventions. Mention them and you often start a flame war . . .

This applies to preprocessor stuff as well. (cpjust mentioned this.) It's a convention inherited from C, and it's reasonably widespread.

I use a special naming convention where if the next letter in the word as ascii code is equal to the start of the next letters ascii code I switch the letter to the third letter if exsisting and delete it and type something random.

OK, that just caused my brain to crash... I sure hope you're just being sarcastic though.
